11; all whom "it may concern:

Be it known that I, Leon Bane, a citizen pfthe- United States, residing in New York, in the borough of Manhattan, county and "State of-Ne'w York, have invented certain new and Improvements .in' Molds for Concrete'WTalls, of which the following is a,

specification.

This invention relates to an improved mold'for concrete construction by which concanbe cast with great facility and of any desired thickness for the construction of. buildingslof all kinds; and for this urpose the invention consists in the novel eatures of construction whic will be fully described hereinafter and final yg ointed out in the claims. a In the accompanying drawings, Figure 1 represents a perspective view showing my lmpro'ved upright. mold-supports placed in position on the foundation-wall, Fig. 2 -is a side-elevation of one section of the mold,

Figs; 3 and 4.- are respectively a horizontal 2.

section on line 3, 3, Fig. 2, and a vertical transverse section on line 4, 4, Fig. 2, Fig. 5 1s a vertical transverse section showlng the connection of the tier of lower supports with the next tier of supports above the same, 30

Fig. 6 is a vertical transverse section through an outside upright showing it in position for making concrete foundation-walls, and Fig. 7 is a detail horizontal section through an upright sup ort of modified form.

Similar c aracters of reference indicate corresponding parts throughout the several 'fi Referring to the drawings, a represents the upright supports of my improved mold for making concrete construction. Each upright support is formed of two separate supports -an inside and outs de one, each support'being made in approximately I-sh'aped cesses of cross-section and composed of intermediate wooden blocks a? plates 0 I Wooden anels 3 are dropped intothe rethe uprights at both ends, said wooden panels bein formed of overlapping sections having ra beted to and bottom and outer and inner edges, as shown clearly at p 1nFig. 4 ,so as to. form a smooth interior surface in line with the inner'plates of each upright. The. outer and inner sections of each upr ght a're' connected by transverse bolts d, which are threaded at both ends and applied to the exterior plates of the uprights by means of" nuts al as shown in Fig. 7 Between the inner plates of an outer and inner upright is interposed on each transverse connecting bolt a thimble d by which the desired thickness of the concrete wall to be cast ,in the mold is obtained. The thimble (1 may be made of sheet-metal, pasteboard, etc., and

moved from the same, the transverse hole formed b the thimble being filled in with cement a ter the concrete wall has set and has dried sufliciently. are :made of metal, it is preferable to sur- When the thimbles round the same by a thin shell of paper, pasteboard, or other material that can remain in the wall, but that will permit the convenient removal of the metallic thimbles. The panel-sections p are also rabbeted at their side-edges, as shown at W, so as to fit over the projecting portions of the plates a so-that the inner surface of the panel-sections is flush with the inner surface of the plates (1 as shown in Fig. 3. Thecorner uprights c are made of rectangular shape, as shown in Fig. 3, but-are constructed of an intermediate angular portion 0 and angular outer and inner plates 0 .In this case the connecting bolts (6 extend diagonally from the angular inside support to the angular outside support, as shown in Fig. 3, the inclosing thimbles 0Z being made in the same manner as the thimbles pf the upright support a. In some cases each outer and inner support may be made of separate sections, as shown in-Fig 7. In this construction the outerplates a are divided longitudinally and the bolts d pass through the space between their adjacent edges. The sections of the outer plates are connected with the blocks a by means of 'bolts a the heads of which are countersunk in said blocks, as shown, while the sections of the outer plates are heldin position by means of nuts at the outer ends of said bolts. By this arrangement the panels may be removed, after first removing the cutter plates by unfastening olts a =Thus the panels the nuts on the v may be readily removed without taking down the upri ht support as a whole.

The connecting bolts d for the outer and inner uprights are preferabl arranged near the lower and upper ends of the same, the lower bolts serving for the purpose of clamping the uprights to the foundation or other well, as shown in Fig. 2. Both the outer and inside uprights are provided with outwardly-cent flanges f at their lower and upper ends which are provided with boltholes so as to permit the attaching of the next tier of uprights to the lower tier of uprights, so that the next section of the wall can be cast onto the lower Wall -':;ection. After the lower concrete-wall section has sufficiently dried, then the lower uprights are removed by withdrawing the bolts and thimbles, and then are applied by means of fastening bolts P which pass through. the

flanges j to the third'tier, and so on until the wall is completed.

fhcn foundatiomwalls are to be made only outer uprights are employed. The

earth is dug out to the required thickness of the wall, as'sho'wn in Fig. 8 then the outer uprights are placed in position thereon, together with their wooden panels 72. The uprights are then supported on hottompieces 6 and supported in upright position by inclined braces & and top-pieces 1 7* which secured in position by means of spikes, as shown in Fig. 6 "When the foundation is completed to the proper height it permits the attaching of the outer and inside uprights, as shown i tor the lower concrete wall is comp sec ond tier of uprights is attached to th i wear tier of uprights and next section of the wall completed, and so on, until the outer and partition walls of the building are completed. v

Having thus described my invention, i cl irn as new and desire to secure by Letters litent:

In a mold for concrete constructions,

the combination of outer and inner uprights,

the combination of outer and inner uprights,.

each of which comprises an inner plate an intermediate block, and an outer plate composed of sections removably attached to said block, a bolt connecting said outer and inner uprights and passing through the spaces between the sections of the outer plates, and

a thimble surrounding said bolt and by which the inner plates are spaced from each other.

In testimony, hat Iclairn the foregoing as my lnventlon, l have signed my name in presence of two subscribing witnesses.
